HU64 4-Channel Smart SMS Temperature and Humidity Controller

Warehouse temperature control is a means to maintain the conditions of warehouses and cold storages with the best product quality and reduce losses related to material spoilage. Storage warehouses for food-dairy-sanitary-medical-paper-clothing-rubber and... all should be within a certain range of temperature and humidity so that their quality does not change during the storage period. In order to store these materials in roofed warehouses, cooling and heating systems are generally used to keep the temperature within the permitted range of the product, but sometimes the failure of the heating and cooling systems or their failure will cause the temperature or humidity to go out of the standard range. If the warehouse situation remains the same, in the case of food products, a delay of more than 1 day may cause them to spoil, and in the case of warehouses that store sanitary goods, the sensitivity of the matter is the same, but the existence of such problems should not cause spoilage. What is the solution if the goods are delivered prematurely or their quality is reduced? The solution is to use warning systems that can measure the temperature and humidity of the warehouse at any moment and give a warning to the employer and the system maintainer if the acceptable range is exceeded. Warnings in I-systems can be in the following forms 1-Warning in the form of a siren 2-Warning in the form of an optical flasher 3- SMS alert 4-Warning in the form of a voice message Each of the above methods alone and together can inform the employer of the existence of a warning so that a solution can be thought of Work resume Photos of projects

Smart server room and intelligence server room is a topic that these days is a lot of noise these days, the smart server room refers to places that, using electronic welfare systems, provide more safety to its managers and ultimately create a good sense of server room maintenance \r\n\r\n\r\nOf course, two groups of individuals are intelligent to control the server room environment, which is the first category of managers who have recently encountered a crisis in the server room where the lack of intelligent server room system has caused a crisis and damages in hardware and data, and the second category are managers who have received non -Certificate or Certificate of Certificates.\r\n\r\n\r\nEquipping the server room intelligent control can happen with any brand, but the service by all brands is not the same and reliable. It is necessary for the IT manager to have an obsessive -compulsive intelligent system in order not to regret the wrong choice in the future.\r\nSee the project photos here\r\nhttps://pishransa.com/pictures/\r\n\r\nIn the SRC2.2 system, a powerful industrial controller is used as a systemic brain, which is the world's most prestigious industrial processor. This processor does not even use 10 % of its capabilities in the most sophisticated server room in the server room.\r\nIn several glances, the intelligent server room can raise the opinion of users to encourage it to be implemented.\r\n\r\nSee our resume here\r\nhttps://pishransa.com/projects/\r\n\r\n1) With the Smart Server Room we can say the server room will move toward integration\r\n\r\nFor example, control of all areas in the server room, including racks and UPSs and electrical and physical parameters by the central panel and the organization's software console in each of the rooms of the organization will be.\r\n\r\n\r\n2) The smart server room has the ability to create more prosperity for the user\r\n\r\nControlling every single parameter that can be traumatic in some situations and the room is in crisis will eliminate the sense of confusion.\r\n\r\n\r\n\r\n3) The smart server room provides more safety for users in equal conditions\r\n\r\nThe existence of gas leak control systems, water control and warning, smoke and fire alert with temperature and humidity gives the manager a good sense of control and safety, even smart systems at the time of the user's departure from the server room, and the power of the electrical equipment and the potential defects, as well.\r\n\r\n\r\n4) The Smart Server Room will have security against theft and unauthorized entry\r\n\r\nIntelligent systems in addition to temperature monitoring use Access to Exit and Exit This System.

FNIRSI Function Generator Model SG-004A; Multifunction Calibrator 0–24mA/0–24V with Frequency Output up to 10kHz for PLC and DCS For engineers who need a truly versatile tool If you constantly switch between multiple devices for debugging PLCs, simulating DCS, adjusting valve positioners, or testing inverters, the SG-004A shines exactly where ordinary tools fall short. This multifunction signal generator/calibrator from FNIRSI provides 0–24mA current, 0–24V voltage, frequency up to 10kHz, and mV input/output (for thermocouple simulation) in a compact, battery-powered unit; along with real-time waveform display, input-to-output signal conversion, and history recording—everything needed for fieldwork and quick commissioning. Why is the SG-004A the first choice for fieldwork and commissioning? Multiple vital signals in one device: current source, voltage source, frequency/pulse, and mV for thermocouples—instead of carrying several separate calibrators. Industrial-level sourcing and sinking: 0–24mA and 0–24V cover the 4–20mA and 0–10V standards in PLC/DCS and drive inputs/outputs. Frequency up to 10kHz: suitable for testing high-speed pulse/counter inputs of PLCs and simulating common frequency signals. Suitable accuracy and resolution for instrumentation: 0.001mA and 0.001V resolution; industrial-class accuracy (about 0.2% depending on mode). Live display and data logging: view signal curve in real-time and review history for evidence-based troubleshooting. 3000mAh battery with Type-C charging: approximately 10 hours of operational use and long standby; perfectly suited for field projects. 2.4-inch color display: high readability in varying industrial lighting conditions. Pocket-sized: 112×77×21 mm and only 167 grams—always handy without hassle. Deeper engineering; what makes a practical difference 0–24mA current source with precise control: simulate 4–20mA for calibrating PLC analog inputs, testing valve positioners, and checking current loop behavior. 0.001mA resolution lets you make fine step adjustments and measure hysteresis. 0–24V voltage source with 1mV steps: calibrate 0–5V and 0–10V inputs/outputs on analog cards, drives (VFD/inverters), and controllers. Frequency output up to 10kHz: stimulate high-speed digital inputs (HSC/Counter), simulate speed sensors, or test pulse counting paths in PLCs. mV input/output for thermocouples: simulate and receive mV thermocouple signals for testing and matching temperature channels. Ideal for calibrating measurement chains without heat sources. Input-to-output signal conversion: map one input simultaneously to a desired output signal (e.g., convert 4–20mA to 0–10V) and instantly see loop response—ideal for testing transmitters and I/O cards. Auto Lift (Ramp) output program: generate controlled ramps (step or continuous) for process testing—check valve start points, dead zones, response speed, and stability. Real-time curve and history: observe system behavior live and keep history for later analysis—data-driven troubleshooting instead of guesswork. MODBUS communication support: integrate into industrial control environments and digital workflows. Use cases that shorten project delivery time PLC debugging and I/O commissioning: inject 4–20mA to AI input, 0–10V to AO, and pulses up to 10kHz to high-speed DI—match control software to field reality before process commissioning. DCS simulation in commissioning: test instrumentation loops, signal mapping, and alarm/interlock checks with programmed ramps. Valve positioner adjustment: 4–20mA current ramp to check hysteresis, repeatability, and zero/span points; observe response on the live curve. Instrument testing and calibration: verify and adjust pressure/temperature/flow transmitters with stable reference signals—no bulky lab equipment needed. Inverter (VFD) testing: verify 0–10V/4–20mA analog inputs and frequency inputs; simulate speed commands and observe drive behavior.
